使用以下内容制作缓冲图像和绘制像素之间有什么区别:

private BufferedImage img;

img

变量并使用img的图形来做:

img.getGraphics().drawImage(/*image*/, x, y, observer);

我一直在努力让我的窗户工作.我正在看MSDN页面如何制作一个窗口,我看不出差异.当我运行我的程序时,它会出现一个消息框,上面写着NO WINDOW.

static const LPSTR CLASSNAME = "Win32Window";

LRESULT CALLBACK WndProc(HWND window, UINT msg, WPARAM wParam, LPARAM lParam)
{

    switch (msg)
    {
    case WM_DESTROY:
        PostQuitMessage(0);
        break;
    default:
        DefWindowProc(window, msg, wParam, lParam);
        break;
    }

    return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR cmdLine, int nCmdShow)
{
    WNDCLASSEX wcex;

    wcex.cbSize = sizeof(WNDCLASSEX);
    wcex.cbClsExtra = 0;
    wcex.cbWndExtra = 0;
    wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
    wcex.hCursor = LoadCursor(hInstance, MAKEINTRESOURCE(IDC_ARROW));
    wcex.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_APPLICATION));
    wcex.hIconSm = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_APPLICATION));
    wcex.hInstance = …
